Effect of differences in vascular anatomy on surgical outcomes of left pancreatectomy: a retrospective study.
Article in World journal of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMinimally invasive left pancreatectomy (MILP) is increasingly performed worldwide, necessitating the need for improved understanding of vascular anatomy during surgery. However, the effect of differences in vascular anatomy on surgical outcomes remains unclear. In this study, we aimed to evaluate the effect of vascular anatomical variations on surgical outcomes and identify factors that influence open and minimally invasive surgery (MIS) outcomes.
methodsThis was a single-center retrospective study involving 123 patients who underwent left pancreatectomy (LP). We analyzed the correlation between vascular anatomical variations, namely, (i) the root of the splenic artery (SpA; types 1 and 2), (ii) the parent artery of the dorsal pancreatic artery, (iii) confluence patterns of the left gastric vein, and (iv) the inferior mesenteric vein, and surgical outcomes. We also performed a risk analysis of prolonged operation time, considering surgery-related factors.
resultsSpA type 2 was only significantly associated with longer operation time (p < 0.01) in LP procedures. In all LP cases, the pancreatic resection line (above the portal vein: odds ratio [OR] 3.47; 95% confidence interval [CI] 1.69-11.18; p < 0.01), the SpA type (type 2; OR 2.77; 95% CI 1.16-6.94; p = 0.02), and surgery type (MIS; OR 5.24; 95% CI 2.17-14.00; p < 0.001) were independently associated with prolonged operation times. In open-LP cases, high body mass index (> 24 kg/m
conclusionsSpA type 2 may negatively affect surgical outcomes. Therefore, it is important to recognize and approach vascular anatomy appropriately. MIS, especially robotic surgery, may be effective in mitigating the negative effects of variations in vascular anatomy.
